Puppeteer 3.3.0 crashes Firefox Nightly 79 when using UTF8 in ElementHandler.type

Consider the following script

const puppeteer = require( "puppeteer" );

async function main() {
  try {
    const browser = await puppeteer.launch({
      "product": "firefox",
      "headless": false,
      "devtools": false,
      "slowMo": 30,
      "ignoreHTTPSErrors": true,
      "executablePath": "/etc/firefox-nightly/firefox"
    });
    const page = await browser.newPage();
    await page.goto( "http://todomvc.com/examples/react/#/" );
    const elh = await page.$( "input.new-todo" );
    await elh.type( "ưxx111" );
   
    await browser.close();
  } catch ( e ) {
    console.error( e );
  }

}
main();

If I use in await elh.type( "abc" ); any ASCII everything works perfect, but with "ưxx111" it crashes Firefox with fatal error:

A quick solution is to add into “/puppeteer/lib/cjs/puppeteer/common/USKeyboardLayout.js” the chars you’ll use.

For example, for “ê”, append the line to main object:

ê: { keyCode: 234, key: 'ê', code: 'KeyÊ' },

Run this function to generate and paste into the USKeyboardLayout.js:

function charcodes(char) {

return `${char}: { keyCode: ${char.charCodeAt(0)}, key: '${char}', code: 'Key${char.toUpperCase()}' },`

}

for(let each of ‘êÊáéíúó’){ console.log(charcodes(each)) }

Hope it helps 😃
